Article Synopsis
  • - The study investigated how adolescents with clinical depression and their parents perceive the causes of the depression, focusing on the overlaps and differences in their beliefs.
  • - 34 adolescents with depression and their parents were interviewed separately to gather insights about personal, social, and school-related factors influencing the adolescents' feelings.
  • - Results showed that parents generally have a good grasp of their child's beliefs but often underestimate their insights, particularly regarding the cumulative effects of stress; understanding these differences could be beneficial in therapy.

Adolescents with depression tend to perceive behavior of parents as less positive than adolescents without depression, but conclusions are based on retrospective reports assessed once or over long time intervals, with the risk of memory biases affecting the recall. The current study used ecological momentary assessments to examine the link between adolescent affect and the amount of warmth and criticism expressed by both mothers and fathers in families with adolescents with depression versus adolescents without psychopathology in daily life. It also explored the possible bias by assessing parenting on the momentary, daily (EMA), and retrospective level.

Introduction: In the Netherlands, bariatric surgery in adolescents is currently only allowed in the context of scientific research. Besides this, there was no clinical pathway for bariatric surgery in adolescents. In this paper, the development of a comprehensive clinical pathway for bariatric surgery in adolescents with severe obesity in the Netherlands is described.

Social interactions, spending time together, and relationships are important for individuals' well-being, with people feeling happier when they spend more time with others. So far, most information about the frequency and duration of spending time together is based on self-report questionnaires. Although recent technological innovations have stimulated the development of objective approaches for measuring physical proximity in humans in everyday life, these methods still have substantial limitations.

Objectives: Some young individuals participating in sports activities may encounter lower leg muscle pain and tightness, potentially indicating chronic exertional compartment syndrome (CECS). While muscle pressure measurement is typically recommended for diagnosis, it is invasive and associated with low sensitivity and specificity. Thus, there is a need for novel diagnostic approaches.

Background: Surgery can lead to curation in colorectal cancer (CRC) but is associated with significant morbidity. Prehabilitation plays an important role in increasing preoperative physical fitness to reduce morbidity risk; however, data from real-world practice is scarce. This study aimed to evaluate the change in preoperative physical fitness and to evaluate which patients benefit most from prehabilitation.

Eye contact improves mood, facilitates connectedness, and is assumed to strengthen the parent-child bond. Adolescent depression is linked to difficulties in social interactions, the parent-child bond included. Our goal was to elucidate adolescents' affective and neural responses to prolonged eye contact with one's parent in nondepressed adolescents (HC) and how these responses are affected in depressed adolescents.

Article Synopsis
  • This study explored the emotional dynamics within family triads (adolescents and their parents) by examining how their feelings of happiness, sadness, relaxation, and irritation interact in daily life.
  • Researchers analyzed data from 60 families over 14 days, using advanced modeling techniques to understand how emotions were related both in real-time and over time between parents and adolescents.
  • The findings not only highlighted the bidirectional influence of affect states within families but also provided insights for improving future research on family emotional interactions, including considerations for missing data and study design.

One of the most prevalent nonverbal, social phenomena known to automatically elicit self- and other-referential processes is eye contact. By its negative effects on the perception of social safety and views about the self and others, childhood emotional maltreatment (CEM) may fundamentally affect these processes. To investigate whether the socioaffective consequences of CEM may become visible in response to (prolonged) eye gaze, 79 adult participants (mean [M] = 49.

Aims: In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED.

Background: Adolescents with depression exhibit negative biases in autobiographical memory with detrimental consequences for their self-concept and well-being. Investigating how adolescents relive positive autobiographical memories and activate the underlying neural networks could reveal mechanisms that drive such biases. This study investigated neural networks when reliving positive and neutral memories, and how neural activity is modulated by valence and vividness in adolescents with and without depression.

Background: Parent-adolescent interactions, particularly parental criticism and praise, have previously been identified as factors relevant to self-concept development and, when negative, to adolescent depression. Yet, whether adolescents with depression show aberrant emotional and neural to parental criticism and praise is understudied.

Methods: Adolescents with depression ( = 20) and healthy controls ( = 59) received feedback supposedly provided by their mother or father in the form of negative ('untrustworthy'), neutral ('chaotic'), and positive ('respectful') personality evaluations while in an MRI-scanner.

Background: Multimodal prehabilitation programmes are increasingly being imbedded in colorectal cancer (CRC) pathways to enhance the patient's recovery after surgery. However, there is no (inter)national consensus on the content or design of such a programme. This study aimed to evaluate the current practice and opinion regarding preoperative screening and prehabilitation for patients undergoing surgery for CRC throughout the Netherlands.

Background: Despite the increasing implementation of selective histopathologic policies for post-cholecystectomy evaluation of gallbladder specimens in low-incidence countries, the fear of missing incidental gallbladder cancer (GBC) persists. This study aimed to develop a diagnostic prediction model for selecting gallbladders that require additional histopathological examination after cholecystectomy.

Methods: A registration-based retrospective cohort study of nine Dutch hospitals was conducted between January 2004 and December 2014.

Eye contact is crucial for the formation and maintenance of social relationships, and plays a key role in facilitating a strong parent-child bond. However, the precise neural and affective mechanisms through which eye contact impacts on parent-child relationships remain elusive. We introduce a task to assess parents' neural and affective responses to prolonged direct and averted gaze coming from their own child, and an unfamiliar child and adult.
